The exploration of synthetic methods involving the formation of new chem. bonds at both the nitrogen and carbons atoms of the isocyano group would largely enrich the structural diversity of compounds Herein, we disclosed a silver-catalyzed difunctionalization of the isocyano group with cyclic oximes. This method can generate a great array of structurally novel and interesting pyrimidinediones and features excellent atom economy, good functional group compatibility, and amenability to late-stage modifications. This study involved multiple reactions and reactants, such as Methyl 2-(5-oxo-4,5-dihydroisoxazol-3-yl)acetate (cas: 96530-57-3Computed Properties of C6H7NO4).
Methyl 2-(5-oxo-4,5-dihydroisoxazol-3-yl)acetate (cas: 96530-57-3) belongs to isoxazole derivatives. Isoxazoles are aromatic heterocycles containing an N–O bond. The weakness of this bond allows the ring opening of these heterocycles under reductive conditions. As with isoxazolines, isoxazoles may be cleaved using low-valent titanium obtained from the Kulinkovich reaction.This procedure affords enaminoketones from 2,4-substituted isoxazoles.Computed Properties of C6H7NO4
